From time to time every day, WPMU will suddenly log me out from the admin panel. Sometimes it even happens multiple times in an hour. This has been going on for a while but it *seems* to have gotten worse recently.
I haven't been able to reproduce the bug in my dev environment, which has the same code as my production environment but not the same content. That said, I don't spend nearly as much time in the dev env so perhaps I'm not there long enough to create the conditions for the bug to appear.
I'm pretty sure the problem appeared after upgrading to 2.7.1 a while ago.
Anyone seen anything like this? I couldn't find anything elsewhere in the forums.
